Product Description

Lightweight Aluminum Silicate Fiber Board Low Density Backup Insulation Panel

Product Description

Aluminum Silicate Fiber Board, also known as ceramic fiber board or alumina-silicate insulation board, is a rigid high-temperature insulation board formed from high-purity alumina-silicate fibers in a wet vacuum process. The forming method gives even fiber distribution and consistent density for a strong, dimensionally stable board.

This lightweight, low density grade keeps weight and thermal mass to a minimum, which lowers the load on furnace shells, steel structures and portable equipment. It is a good choice for backup insulation behind hot-face materials, for removable covers and hoods, and for linings that have to be moved or handled often.

Even at low density the board holds its shape under load and resists thermal shock and vibration, and it is non-combustible and chemically stable in normal service.

A small amount of organic binder gives handling strength and burns off on first heating around 250–400°C with a light, brief smoke. Panels cut cleanly and fit quickly with ordinary tools.

Product Features

Lightweight and Flexible – Low weight eases handling and cuts structural load.

Low Density Board – Keeps thermal mass low for fast response.

Backup Insulation Panel – Works well behind hot-face refractory layers.

Excellent Thermal Insulation – Even density limits heat loss.

Class A1 Non Combustible – Inorganic board adds passive fire protection.

Easy Installation – Light panels are fast to cut and fit.
